VBand setup and training guide

What is VBand (Virtual CW Band)?

VBand is a browser-based platform from Ham Radio Solutions that lets you send and practice Morse code online—solo or with others—using your real paddle/straight key or just a keyboard. Think of it as a safe, low-pressure "virtual band" for CW practice and QSOs without radios, antennas, or propagation.

Why train here on the VBand TX Trainer?

  • • Built for real paddles: Works with VBand USB paddle interfaces for authentic timing and "fist".
  • • Advanced drills: Real words, abbreviations, callsigns, Q-codes, frequency/top-word sets, and mixed sessions.
  • • Precise timing: Straight key, Iambic A/B, Ultimatic & Bug modes with accurate element/spacing controls.
  • • Audio you can trust: Zero-drop sidetone options (pitch, waveform, rise time) for clean keying feedback.
  • • Made for progression: Start at your comfort speed and scale toward high-accuracy contest-grade sending.
